The second detection unit which is arranged between the first detection unit and the laser marker unit is electrically connected with the position compensation system. The position compensation system is electrically connected with the laser marker unit. The beneficial effect of the utility model lies in that, by arranging the second detection unit, the related position data arrayed by the semiconductor chip in the pallet can also be treated beside the position parameters and can be sent to position compensation system to accept compensation. Furthermore, by arranging the second detection unit, the detection efficiency can be enhanced.
Description
Technical field
The utility model belongs to a kind of certification mark unit, especially refers to a kind of certification mark unit that is used for the semiconductor array in the pallet is carried out the pallet laser marking system of mark.
Background technology
After semiconductor integrated circuit is produced, the manufacturer tend to these through mark on the packaged integrated circuits on some information, as manufacturer's title, lot number, brilliant circular horn etc., so that statistics and these products differences are come.Semi-conductive encapsulating material is generally epoxy resin, in the prior art, also has multiple to its method of carrying out mark.
Be to use at first pass seal technology and device as, making ide or pressure roller print surface to integrated circuit with ink.This weak point of view altogether is that because ink parches and needs a period of time, therefore, for guaranteeing yield rate, labeling effciency is lower; After mark was finished, because ink invests the integrated circuit packaged surface, so its abrasion resistance was not strong, and is subjected to ambient humidity, Temperature Influence easily.
In order to overcome the deficiency that tradition passes seal technology, occurred in the prior art with the technology of laser beam at packaged integrated circuits device surface tab character and pattern, the principle of this technology is to produce laser beam by Laser Devices, burn the part encapsulating material, thereby make the part of burning have different reflection characteristics with other parts, like this, by being placed on light source following time, can see literal, the pattern of the part of burning through the device of mark.
At above-mentioned laser labelling technology, multiple implementation and system in the prior art, wherein a kind ofly adopted a kind of like this structure, had a conveyer, be used for the device after the encapsulation is transmitted one by one, after by a plurality of sensor detecting devices the position being detected, send into a laser marking device, carry out mark one by one, after mark finishes, detect defect ware by a testing agency, by a handsetting mechanism defect ware is dialled from transfer system at last.Yet, there are a lot of weak points in this system, at first, also be most important, because it is each semiconductor devices through encapsulation need experience the transmission of conveyer, therefore higher to the requirement of strength of device, and it is little for the volume of present appearance, during low novel of intensity is unthinkable, and in transmission course, device will be worn even lose efficacy.Secondly, also often occur blocking, falling phenomenons such as part again on the transmission path of transmitting device, this just needs system in multiposition sensors configured more, and improves control program, thus this expense that has just increased system's design and safeguarded; In addition; because laser energy is very strong in the laser labelling; therefore; for protection operating personnel's purpose, need gate be set to guarantee laser cell work down in confined space, so respectively from the side of going into, go out of laser labelling unit; when each element on the conveyer is carried out the mark operation; all need the switch gate once, this not only greatly reduces the life-span of gate, has also reduced operating efficiency simultaneously.
In view of the situation, of the prior artly provide a kind of like this laser marking system, it adopts device array is arranged on the pallet, wherein, grid can be arranged in order to immobilising device on the pallet, can be suitable for different grids according to size, the structure of number of devices and device.Pallet is transported to place, laser labelling unit and carries out mark.
Yet, in labeling process, because existing scanning testing agency adopts the one-level detection, promptly to image obtain and Treatment Analysis all is to be finished by a scanner uni detection system, and can only the detection chip location parameter, it is bad therefore to detect effect, and efficient is not high yet.
The utility model content
A purpose of the present utility model is to solve weak point of the prior art, and a kind of certification mark unit that is used for the pallet laser marking system is provided.
For achieving the above object, the certification mark unit that is used for the pallet laser marking system of the present utility model comprises
First detecting unit, the laser labelling unit.According to the utility model, also comprise second detecting unit, with the position compensation system, described second detecting unit is arranged between first detecting unit and the laser labelling unit, described second detecting unit is electrically connected with described position compensation system, and described position compensation system is electrically connected with described laser labelling unit.
Further, described second detecting unit comprise the frame with back timber, the driver element that is installed on frame and by drive unit drives along the reciprocating scanning element of back timber stepping.
The beneficial effects of the utility model are, by second detecting unit is set, can handle the relevant position data of semiconductor core chip arrays in the pallet except that location parameter, and deliver to the position compensation system and compensate.In addition, by second detecting unit is set, detection efficiency is improved.

Fig. 1 is the stereogram that is used for the certification mark unit of pallet laser marking system of the present utility model.
Fig. 2 is the schematic diagram according to the certification mark unit of first kind of specific embodiment of the utility model.
Fig. 3 is the systematic schematic diagram according to the certification mark unit of a kind of specific embodiment of the utility model.
The specific embodiment
The utility model relates to a kind of certification mark unit, detects and mark in order to the semiconductor element that the array in the pallet that transmits on the connecting gear of pallet laser marking system is piled up, and below in conjunction with accompanying drawing, feature of the present utility model is elaborated:
Fig. 1 is the stereogram of the utility model structure, and with reference to Fig. 1, the certification mark unit that is used for the pallet laser marking system in first kind of specific embodiment of the utility model comprises first detecting unit, 1, the second detecting unit 2, laser marking unit 3.
The structural similarity of first detecting unit 1 and second detecting unit 2, wherein, with reference to Fig. 2, second detecting unit 2 is as known in the prior art, structurally, has frame 21, driver element 22 gear units 23 and detecting unit installing rack 24 and detecting unit 25, wherein detecting unit 25 is installed on detecting unit installing rack 24, and driver element 22 driving gear units 23 drive detecting unit installing racks 24 move along the crossbeam of frame 21.The signal output part of second detecting unit, as shown in Figure 3, the input of link position bucking-out system 3, after position compensation system 3 receives the transmission image of second detecting unit 2, image is analyzed, obtain the deviate of image and standard grid, and the position deviation of each grid is carried out record; After this, these deviates are sent in the control system 31 of laser labelling unit 3.
As is known in the art, the control system 31 of laser labelling unit is generally according to input data selected marker position and angle, by to control system 31 input deviation data, can compensate the position deviation during the semiconductor in the pallet, thereby reduce the number of rejects and seconds rate.
Being the utility model preferred embodiment only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
